Regulation of Indole Signalling during the Transition of E. coli from Exponential to Stationary Phase. [PDF]
PLoS ONE, 2015 During the transition from exponential to stationary phase E. coli produces a substantial quantity of the small, aromatic signalling molecule indole. In LB medium the supernatant indole concentration reaches a maximum of 0.5-1 mM.

Indole at low concentration helps exponentially growing Escherichia coli survive at high temperature. [PDF]
PLoS ONE, 2017 A culture of stationary phase Escherichia coli cells has been reported to produce copious indole when exposed to high temperature (50°C), and this response has been proposed to aid survival.

Acta Biomedica Scientifica, 2022 Signaling molecules such as indole (product of tryptophan catabolism) and (p)ppGpp (stringent response regulator) are involved in regulation of physiological processes in bacterial cells aimed to adapt to antibiotics and stresses.

Microorganisms, 2021 Gut microbiota metabolizes tryptophan into indole, which can influence brain and behavior. Indeed, some oxidized derivatives of indole, formed in the liver, have neuroactive properties, and indole overproduction by the gut microbiota induces an anxio ...

Illumina MiSeq Sequencing Reveals Diverse Microbial Communities of Activated Sludge Systems Stimulated by Different Aromatics for Indigo Biosynthesis from Indole. [PDF]
PLoS ONE, 2015 Indole, as a typical N-heteroaromatic compound existed in coking wastewater, can be used for bio-indigo production. The microbial production of indigo from indole has been widely reported during the last decades using culture-dependent methods, but few ...

Altered virulence of non-indole-producing pathogenic bacteria by indole signaling [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 Bacteria naturally live in a multispecies community. Cell-to-cell communication is therefore crucial for bacteria to adapt, survive, and regulate virulence.

Indole Inhibits IncP-1 Conjugation System Mainly Through Promoting korA and korB Expression
Frontiers in Microbiology, 2021 Indole works as an interspecies signal molecule to regulate multiple physiological activities, like antibiotic resistance, acid resistance, and virulence. However, the effect of indole on conjugation is unknown.

Antibiofilm and Antivirulence Properties of Indoles Against Serratia marcescens
Frontiers in Microbiology, 2020 Indole and its derivatives have been shown to interfere with the quorum sensing (QS) systems of a wide range of bacterial pathogens. While indole has been previously shown to inhibit QS in Serratia marcescens, the effects of various indole derivatives on

RpoS and indole signaling control the virulence of Vibrio anguillarum towards gnotobiotic sea bass (Dicentrarchus labrax) larvae. [PDF]
PLoS ONE, 2014 Quorum sensing, bacterial cell-to-cell communication with small signal molecules, controls the virulence of many pathogens. In contrast to other vibrios, neither the VanI/VanR acylhomoserine lactone quorum sensing system, nor the three-channel quorum ...

Indole contributes to tetracycline resistance via the outer membrane protein OmpN in Vibrio splendidus [PDF]
, 2020 As an interspecies and interkingdom signaling molecule, indole has recently received attention for its diverse effects on the physiology of both bacteria and hosts. In this study, indole increased the tetracycline resistance of Vibrio splendidus.
